[TIP] What strategies to you use to factor seleniums tests to avoid duplications of the same or similar test steps?

Tarjei, Thank you for pointing out Canoo WebTest.  At first glance, it seems
to have a feature set very much in line with what I'd like.  I'll have to
play around with it a bit.  Thanks again.

I wasn't referring to testcases, but subsets of testcases (such as logging
on and getting to a given screen) that could be factored out into common
code.  Most of the time this would likely be setup and tear-down, but
sometimes it might not be.  Factoring out common operations that are part of
setup and/or teardown is really what I was talking about.

Automatically not running some class of tests is an intersting concept.  The
idea here seems to be to interpret testcase action words using more than one
execution engine, where the execution engine in a sense defines a
permutation of the testcase.  (Ie:  in your case, skipping the
slow/client-based tests while running in a http/server-only permutation.)
Nice idea!  This could be extended or documented with attributes in the
testcases identifying which testcases work in each permutation.  It would be
nice to see our open source test tools evolve to embrace such ideas.  Thank
you for sharing your comments.
